Paper Abstract

The importance of space scale matching of flying direction and object long axis is presented when we measure nutation angle of flying object with slit photography, and a new method to measure nutation angle of flying object combined slit photography and double linear CCD intersection is examined. A brief methodology of nutation angle computing by series double linear image analysis is discussed, and a nunation angle measurement system is designed. A series linear image analysis method is developed to obtain the image position of series point on object long axis at pixel scale, and then the double linear CCD intersection theory is used to find the space coordinate position of various points at actual space scale. They are also put forward in this paper that invalid coordinate data are rejected by line detecting and flying direction data space is decided by perpendicular flying distance of object at CCD sampling interval. At final, a practical test sample is given, and the feasibility of measurement method is proved.
